# EG393

**EG Micro** · Comparators · SOP-8

EG393 from EG Micro, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Open-collector output of comparator A. Requires an external pull-up resistor to a supply rail (typ. 3k-100k). Can sink up to 16mA; absolute-max output-to-ground short-circuit current 20mA. |
| 2 | -INA | input | Inverting input of comparator A. Input common-mode range 0V to Vcc−1.5V; input bias current typ. 25nA, offset current typ. ±5nA. |
| 3 | +INA | input | Non-inverting input of comparator A. Input common-mode range extends down to ground and up to Vcc−1.5V. |
| 4 | GND | power_in | Ground / negative supply reference (V-). Tied to 0V in single-supply operation, or to the negative rail (down to −18V) in dual-supply operation. |
| 5 | +INB | input | Non-inverting input of comparator B. Input common-mode range extends down to ground and up to Vcc−1.5V. |
| 6 | -INB | input | Inverting input of comparator B. Input bias current typ. 25nA; input offset voltage typ. 1.0mV. |
| 7 | OUTB | output | Open-collector output of comparator B. Requires an external pull-up resistor to a supply rail. Can be wired-OR'd with OUTA on a shared pull-up. Sink current up to 16mA. |
| 8 | VCC | power_in | Positive supply. Single-supply range 2.0V to 36V, or +1V to +18V in split-supply operation. Typical quiescent current 0.8mA (independent of Vcc). No bypass capacitor is required for the bias network but standard decoupling is recommended. |

## CAD (KiCad official)

- Symbol: `EG393`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `eg393-etched.step` / `eg393-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `eg393.step` / `eg393.glb` are the bare package body.
